Yup :-) At least of those statistics functions we identified..

That would be a starting point.

Just make sure that if a filter option is not supported the function
returns an error in that case.
For the "ignore errors" options we'll have to provide either an option
to existing subfunctions or implement their counterparts (depends on
"Ignore nested SUBTOTAL and AGGREGATE functions" is similar to SUBTOTAL
with the addition of AGGREGATE.
"Ignore hidden rows" is somewhat similar to how it is handled in
SUBTOTAL, just that SUBTOTAL ignores only filtered rows in the first set
of its options, not all hidden. Actually needs to be clarified if Excel
really ignores all hidden or only filtered. SUBTOTAL has a second set of
options that ignores not only filtered rows but all hidden rows, we also
need to implement that, so AGGREGATE may benefit from it.
